Incidence of Brain Tumors and Mobile Phones: a Population-Based Descriptive Study in Denmark, Finland, Norway:and Sweden, 1974-2003

摘要

Radio-frequency electromagnetic fields emitted from mobile phones have been proposed as a risk factor for brain tumours. Epidemiological data are sparse for longer term mobile phone users, and open questions about prolonged exposures remain. We investigated time trends in brain tumor incidence rates in four Nordic countries [1] to evaluate whether trends in the incidence of brain tumor changed in Denmark, Finland, Norway, and Sweden from 1998 to 2003. We compared them with expected time trends derived from various scenarios of hypothetical risks related to mobile phone use [2].
